- Enforce a default TTL value (one) in SDP if there is none - refs #404
  (it should at least be fine for IPv4 usage)

* added an option to keep the selections in the wizard for a single session. It's enabled by default. (refs #522)

  I420 still not fixed for this bug.

  A simple average of the UV pixels, wasn't giving satisfying results, so I added a bit more logic, to decide based on the transparency value if UY averaging is desireable for the pixels. Produces nice results now, with a very slight shadow somtimes to the right side of the images/glyphs. Looks quite good. 

  Now duration is accurate, but current time is still block based, so on VBR discs the duration of a second may have some weird variations. Getting accurate time is possible (see what was reverted in [12862]), but this will break the relative SET_TIME (might actually go seeking in the wrong direction for instance). The correct fix here is to expand dvdread with a method that checks the TMAPTI IFO table of a Title, to find what block approximately goes with a certain time. (the TMAPTI table is usually in .5 secs interpolation might possibly be required as well) As a backup an estimate can be made using the ADMAP table.

The behaviour of the dvdread module is now equal to that of the dvdnav module when it comes to time and seeking.

* Use the correct pitch values when reading from and writing to pictures (out pitch can differ from in pitch, and there is also visible pitch and visible lines.

Should support deletion through the delete key. But the delete key is not recognized par X11 skins2.

* Fix issues with the deinterlace filter that was using the source picture pitch when writing to the output picture.

* removed the stupid "wizard help window" and replaced the help sheets with calls of NSBeginInformationalAlertSheet. This might be beautified with NSAlerts in the future, since we don't care for 10.2 anymore.

- Clean up
(refs #404)

have to remove it... but i doubt it.

also replaces x-playnow hack with a slightly less ugly hack

vlc vod server can now serve about 5 seconds of video to amino stbs

vlcrc file. This might seem obvious, but many people on the forums don't
seem to understand that.
